摘　　要：移动蓄热技术是缓解能量供求双方在时间、强度及地点上不匹配的有效方式,是合理利用能源及减轻环境污染的有效途径。本文概述了移动蓄热技术的在工业余热回收利用中的研究进展,分析了我国分散式热用户市场,讨论了化学能储热、显热储热、相变潜热储热技术在移动蓄热车应用中的优缺点,其中潜热储热具有储能密度高、体积小、能量供应稳定等特点,在移动蓄热车中有着广阔的应用前景。在此基础上,归纳了应用于不同热源温度的相变材料,并针对其低导热系数问题,总结了几种强化换热技术。指出了移动蓄热技术的发展方向,展望了移动蓄热技术的市场化应用前景。The mobilized thermal energy storage （M-TES） technology can make the ＂when＂ and ＂where＂ of waste heat＇s availability match the ＂when＂ and ＂where＂ of its reuse, which is very attractive. This paper presented a review on the research progress of M-TES technology, and the distributed heat user market in our country was also analyzed. The advantages and disadvantages of the energy storage technology such as chemical energy storage, sensible heat storage and latent heat storage which can be used for the M-TES were also discussed. The latent heat thermal energy storage has the advantages of flexibility, high efficiency and stable heat supply, which is very suitable for mobile heat storage car. The phase change materials （PCMs） to be used for heat source at different temperatures were summarized. Various heat transfer enhancement methods were reviewed and discussed to solve the problem of the low thermal conductivity of the PCMs. What we need to do to promote the M-TES technology was pointed out. And finally the market application of the M-TES technology was prospected.
